RADIATOR.

Specification of Letters Patent.

Patented Feb., 5, 191%.

Application led September 30, 1915.; Serial No. 53,218.

The invention relates to radiator cores for cooling the water in motor driven vehicles; and the object of the improvement is to provide a strong and durable zigzag water way construction in which said water ways are not choked at any point but -are substantially of the same capacity in cross section throughout their length, yet the sheet metal strips forming said water ways are shaped so as to fit onto one another with broad supporting contact surfaces and strong guiding shoulders which insure the quick and easy assemblage of the parts in an eX- -ceedingly strong bracing construction; and

the invention consists in the novel features and combinations hereinafter set forth and claimed. v

lin the drawings, Figure 1 is a front elevation of the radiator of a motor car showing the diamond shaped air iues therethrough. Fig. 2 is a horizontal crosswise sectional view of one of the water ways. Fig. 3 is an enlarged front elevation of a portion ofthe core of the radiator showing the constructionl and arrangement of the same; and Fig'.A 4 is a vertical crosswise sectional view of a portion of the core of the radiator further showing the construction and arrangement A of said radiator core. Fig. 5, is .i perspective view of a portion of one of the sheet metal strips forming the side walls 4of the water ways showing the conformation of the same.

Like numerals of reference refer to corresponding parts in the several views.

The numeral 10 designates the radiator .casing and the numeral 11 designates the core 0f the radiator. rllhe casing 10 has the reservoir 12 in its upper portion above the core 11 and the reservoir 13 beneath the core 11 in the lower portion of the casing 10,

the heated water from the motor'being received in the reservoir 12 and passing down through the water ways 14 of the radiator coreV to the reservoir 13 and from thence to the motor.

The core 11 of the radiator is made up of the zigzag water ways 14 which form diamond shaped op'en ended air lues 15 therebetween when a plurality of said water ways are assembled together. The water ways 14 are each formed by a pair of similarly bent up sheet metal strips 16 which are shaped by a suitable die in the alternating or zigzag form shown so as to provide a practically unobstructed water Way 14:v therebetween, that is, one which has substantially the same. volume in cross section throughout its length though said water way is full of zigzag'bends and shoulders.

The metal strips '16 of each water way have their edges 21 offset toward Tone another and joined to form a fin of double thickness and provide edge reinforcement for said water way. Broad, transversely extending, fiat contact surfaces 17 are offset adjacent each zigzag bend to lie in the same plane as the offset fins 21. r'

The conformation of the flat contact surface '17 in the same plane as the fin or iiange 21 provides a relative narrow angular guide shoulder 18 along the inner edge of said contact surface 17 of a height equal to thev amount of the offset at 21. The Contact surfaces of one water way seat on those of the adjacent water ways when assembled, the shoulders 18 overhanging the outer edges of the opposing contact surfaces to thereby form a strong interlocking joint between. the two strips of the water ways which gives great rigidity to the entire construction. bend are preferably placed in opposing The contact surfaces 17 at each pairs so that they converge toward one ansolder extending up into the joint between each of the contact surfaces 18 and attaeh` ing both ends of the same firmly so that said surfaces 17 are strong and rigid in their holding contact upon one another` ways are preferably enlarged by the recurring angular formation, which arrangement permits the two sheet metal strips 16 being bent up by the same die, since the bends and shoulders in each are the same. The sheet metal strips 16 are preferably attached to one another at their upper and vlower ends by means of the return bend joints 20 though any other means of attachment of these ends would not depart from the invention. l

. This simple core construction with .the water ways 14 having the converging contact surfaces 17 and shoulders 18 is still further braced by means of the joined edges 21 which brace against one another at thev bends 22, as shown in Fig. 3, giving added stiffness tothe Contact joints formed by the contact surfaces 17 and shoulders 18.

It is apparent also that in radiator cores in which it is not Anecessary to deliver a large amount of water therethrough, the

water Ways 14 may be alternated with single zigzag separating strips 16 shaped in substantially the same conformation as for one of the sides of the water way 14.

I claim as new:

In a radiator, pairs of metal sheets formedv to provide vertical series of air flues each of approximately diamond shape in crosssection, the intermediate corners of the diamond shaped iues being provided with substantially L-shaped offsets which face downwardly and the top and bottom ends of two adjacent diamond shaped iiues being connected by substantially .Z-shaped parts formed by contacting relatively wide extensions of the pairs of plates which pro ject beyond said top and bottom ends of the air fines, the air iiues of the respective series being arranged in relatively staggered relation with said L-shaped offsets of one series disposed oppositeto and spaced from the Z-shaped parts of the adjacent series to provide Water passages of substantially equal width throughout, said Z-shaped extensions forming shoulders to hold the plates against upward or downward movement.

In testimon whereof I have aixed my signature in t e resence of two witnesses. LAYTON M. JONES.
